摘要：

The mechanism of the reaction of dichromate with dithizone, 2-oxopropanephosphonic acid, acetylacetone, trifluoracetylacetone and benzoylacetone in organic solvents was studied by the EPR method, which detects the formation of Cr(V) complexes. The solvents most suitable for the formation and stabilization of these complexes are DMF, HMPA and DMSO. It was established that the solvents firstly reduce Cr(VI) to Cr(V), which is then stabilized as complexes by the ligands. © 1979.
